StopTech Slotted & Drilled Sport Brake Rotor

The Stoptech 127.34104L is a front left drilled and slotted brake rotor, a direct alternative to BMW part #34116786392. This 338x26mm rotor fits stock E82 135i front brakes and can be retrofitted to E82 128i and E9X 325i/328i models with factory BMW Performance sports brakes. It features cross-drilling and slotting for enhanced performance with sport pads or in wet conditions. StopTech manufactures this rotor using a "better than OE" approach, incorporating an electrostatic anti-corrosion coating. It is CNC machined from a High Carbon blank disc, which allows for greater heat absorption, reduced deformation ("warping"), improved resistance to surface cracks, and superior overall performance.
